Forget your wallet? No problem if you have your phone and license...

Near
field communications (NFC) is the kind of wondrous future-tech that promises to
bring new convenience to every-day chores like shopping for groceries or
fueling up at the pump. Japanese customers have already been using
NFC-enabled cell phones as credit cards for several years.

Now Google, Inc. (GOOG),
makers of the world's top smartphone operating system, Android, have announced
than NFC will soon arrive for American consumers.

The announcement was made at the Web 2.0 Summit by Google CEO Eric Schmidt, who
will step
down as Google's CEO next Monday. Web 2.0 is an annual
internet-aimed conference held annually in San Francisco, Calif. since 2004.
The company had previously
expressed interested in NFC payments, but had failed to fully
elaborate on how it would execute the billing scheme.

CitiGroup claims to be the largest issuer of credit cards in the world with its
Citi Cards. Much of the company's business is outside the U.S.
MasterCard is second
to Visa (V) in
the U.S., with 171 million credit cards and 123 million debit cards active
within the U.S. [source].

As with standard cards, a fee will be charged to businesses. It's unclear
at this point whether the cardholders (customers) themselves will pay any
additional periodical or spot fees for the service.

What Google did make clear is that it is not getting a cut of any fees from the
card.

It is offering the service for two reasons.

The first is that it makes an attractive selling point for its smartphones.
Top competitors Apple (AAPL)
and Research in Motion (RIM)
lack billing service on their popular U.S. models.

Secondly, Google will track your purchases and says it may use them to try to
better target ads or discount offers at your phone.

As traditional advertising begins to fade, targeted advertising is a booming
business. By direct ads that customers might actually care about, for
example local sales or sales on items the user typically purchase, the uptake
rates are far higher. Everyone from U.S grocery chains like Kroger, to
internet giants like Google, eBay/PayPal, and Facebook are deeply involved in
the field.

The dark side of data mining is that more of your information will be stored
with the potential for compromise. While Google and others have engaged
in efforts to anonymize data to a degree, advocacy groups and U.S. government
officials have expressed concern about data mining and suggested possible legislation to limit its scope.

For now customers choosing to adopt the new Android service, will find
themselves jumping deeper into Google's data mining bid.

Gingerbread is Android's latest operating system version, which features user interface
refinements, battery life improvements, increased web standards support, and
improvements to the OS's copy, cut, and paste routines.

The Software Development Kit for Gingerbread rolled out to developers in
December. Motorola and Samsung appear to have advanced builds of
Gingerbread ready for their smart phones whenever carriers decide to throw the
switch. Builds for Motorola's Droid X and Droid 2 and Samsung's Galaxy S
smart phones have leaked in recent weeks.

Currently Gingerbread is exclusively available through official channels on Google's Nexus S,
which went on sale in December of last year.

NFC requires special hardware, so it's unlikely that phones like the Galaxy S
would be able to support the new technology. For now the Nexus S appears
to be consumer's best bet for getting access in the near future.

III. What is NFC and Where Can You Use It?

Near Field Communication relies on an active device (like a key fob or your
phone) acting as an active (powered) sender and sending a signal to a passive
receiver. Typically the receiver is located within 4 cm of the sender in
order to properly receive the signal.

The technology operates at the 13.56 MHz frequency, well below the frequency
band commonly used with Wi-Fi, 2.4 GHz.

The technology was developed and licensed by Dolby Labs' subsidiary Via
Licensing Corp.

Currently one of the largest makers of NFC readers is Verifone Systems, Inc. (PAY).

There are actually thousands of such devices already employed across America.
Examples include checkout devices that you tap your card against and gas
pump charge devices you tap a key fob against. With the new deal, you
could theoretically use your compatible Android smart phone with most of these
devices.

You may need to have your license ready to present for larger purchases, as with credit cards, to confirm your identity.

A MasterCard sponsored survey by Edgar, Dunn & Co. suggests mobile
payments, the field that NFC billing falls under, will swell to a $618B USD
market by 2016.

It's unclear how the device will coexist with the upcoming Isis billing system from Verizon
Wireless (VZ),
T-Mobile (Deutsche Telecom: DTE),
and other players. It appears, at present, that it will compete with such
a system.

While wireless billing will almost certainly land on the iPhone, on
Blackberries, and on the Windows Phone 7 platform in the near future, it
appears that Google will be the first smart phone OS maker to leverage this
fascinating, if a bit scary technology.

The technology is thought to be relatively secure; it would likely take more
effort to steal your card digital via NFC trickery than it would to steal your
card information from a corporate database.

Yea, but the reasoning behind my post was that if I'm going to pull out my wallet to get my ID, I may as well pull out my CC as well to pay for it since it's also in my wallet. But it would be a different story if I can swipe my phone and punch in some passkey pin to authenticate.

Right now, using traditional CCs: if you pull out your wallet, you've likely got your ID and CC both very handy. In the future: If you're paying with your phone and you still require ID for some reason, you've got to pull out your wallet, and then your phone, unlock it, and fire up the NFS CC funtion (don't want it running all the time). Is it a big deal? No. But why switch to something that is even LESS convenient than what we already have?

So if they used a PIN number similar to Debit transations, I would support an NFC-based CC function for phones. Assuming it didn't cost extra for myself or the vendor. Otherwise I'll just stick with Debit. After all, I don't go anywhere without my wallet anyway.

Since the NFC is attached to a computer (your phone), it opens up the possibility of public/private key encryption. The phone can have a chip which encrypts the card number and some transaction number hash with its private key and the credit card processor's public key. It transmits that encrypted transaction over the net to the credit card processor. The credit card processor then looks up the device's public key, and uses that + their private key to decrypt the transaction.

It'd actually be safer than a card + PIN. That's vulnerable to someone videotaping you typing your PIN and zooming in to get your card numbers. Of course you have to be sure to secure your phone with some unlock PIN or pattern. But for a thief to use that he'd have to videotape it and physically steal your phone, since there would be no way to extract its private key remotely.

How about on a touch screen phone a fingerprint scanner ala biometric unlock - a simple app that "securely verify's you are you" via fingerprints.... wouldn't even require anything more than unlocking your phone & opening said app (which may just be able to rolled up into one NFC app)

Solandri, you're again misinterpreting what I am talking about. I wasn't talking about security, I was talking about convenience. Although for the record, NFC + PIN might be even more secure than NFC alone. Regardless, look at the post I replied to. Then read the article, where they talk about the strong possibility of needing ID in addition to your phone.

Moto was saying that pulling out your phone is the same as pulling out your wallet. I was merely pointing out that if they require ID, now you're pulling out BOTH, which is silly. I'll break it down again.

Non-NFC:If you pull out your wallet, you have the CC and your ID. So if they need your ID (they shouldn't in most cases), you've already got it right there. In Debit + PIN scenarios, they won't need your ID, nor even a ZIP or Phone number.

NFC: Now you're pulling out your wallet, showing ID, and pulling out your phone, unlocking it, and activating NFC. If they used a PIN similar to the debit system, they could make it about as simple as Debit transactions are today.

Is it a big deal? No. Not really. But why make things more difficult and complicated than they are today? Also, if your phone is somehow rendered inoperable (it happens, that's why smartphone insurance exists), now you've lost access to your NFC payment option.

Also, a slightly OT look at a potential near field near future:"Yes, I'd like to pay the $400 fee to get my $2500 iBananaPhone replaced under insurance, but I don't have access to my cards because they are all on my broken phone."
